I recently created an iPhone app using the web based service [obscured] I am able to provision the app and test it on my personal iPhone and iPad, now I just want to submit it to the app store. I have my own Apple Dev license and wish to submit the app to the app store under it, however every time I attempt to do so I receive a notice from Apple that reads:

Invalid Signature - Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target.
